Built from cobalt and vanadium high speed steel with a bright, uncoated finish, this bit delivers the toughness and heat resistance required when cutting through hard and abrasive materials. It features a 0.3189-inch diameter, a 130-degree split point, and a parabolic flute geometry that improves chip evacuation and reduces the need for frequent tool retraction. The straight-cylindrical shank seats securely in standard drill chucks. Machinists and tool-room technicians working in fabrication, manufacturing, and maintenance environments rely on this series for consistent, accurate hole quality.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for screw machine operations and general-purpose drilling where a stub-length tool is preferred for rigidity and reduced runout. It performs across a wide range of workpiece materials including steel, stainless steel, cast iron, hard materials, and non-ferrous metals, making it a versatile choice on the shop floor. The Series A1148 designation places it within a line built to DIN and ISO standards, ensuring dimensional consistency for production and maintenance work alike. Typical users include machinists, tool-and-die makers, and maintenance mechanics.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt and vanadium high speed steel construction for elevated heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003e130-degree split point reduces thrust and improves self-centering on hard materials\u003c\/li\u003e\n  \u003cli\u003eParabolic flute profile promotes efficient chip evacuation at higher feed rates\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration reduces cutting resistance\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank for compatibility with standard drill chucks and collets\u003c\/li\u003e\n  \u003cli\u003eMeets DIN, ISO, and BS specification designations for dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style screw machine length drill bit compatible with workpiece materials including cast iron, hard material, non-ferrous metal, stainless steel, and steel.

Ensure the drill press, lathe, or CNC machine is fully powered down and locked out before changing tooling. Verify chuck or collet runout is within acceptable tolerance before drilling to maintain the tight diameter tolerance of this bit. Follow applicable shop safety standards and machine manufacturer guidelines for feed rate and spindle speed selection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.3189 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.4375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.9000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Length\u003c\/strong\u003e: 0.0745 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt and Vanadium High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.00087 to 0.00000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Hard Material, Non-Ferrous Metal, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A1148\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN, ISO, BS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WALTER-TITEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5057237\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51748786569522,"sku":"5057237","price":39.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d778e31de38b3101e5d48fe228b3dfd1_28bf7c3e-de07-4815-aff7-b007864d3d97.jpg?v=1788898340","url":"https:\/\/voomisupply.com\/products\/walter-titex-5057237-screw-machine-drill-bit-0-3189-in","provider":"Voomi Supply","version":"1.0","type":"link"}
